2020 Subaru Ascent: Common Engine Issues

Hey guys! Are you thinking about buying a 2020 Subaru Ascent or maybe you already own one? It's a great SUV, no doubt, but let’s be real – no car is perfect. The 2020 Ascent has had its fair share of engine issues reported by owners. So, let's dive deep into what those problems are, why they happen, and what you can do about them. Understanding these potential hiccups can save you a lot of headache (and money!) down the road. So buckle up, and let’s get started!

Common Engine Issues in the 2020 Subaru Ascent

When it comes to the 2020 Subaru Ascent, a few engine-related gremlins have popped up more frequently than others. Knowing what these are can help you identify problems early and take swift action.

1. Excessive Oil Consumption

Excessive oil consumption is definitely one of the most talked-about issues with the 2020 Ascent. Some owners have reported that their vehicles are burning through oil much faster than expected. We're talking about needing to add a quart of oil every 1,000 to 3,000 miles – yikes! Now, most engines consume some oil, but this is beyond what’s considered normal.

Why does this happen? Well, there could be several reasons. One potential cause is the design of the piston rings. If they don't seal perfectly against the cylinder walls, oil can sneak into the combustion chamber and get burned along with the fuel. Another possibility is issues with the PCV (Positive Crankcase Ventilation) valve, which can lead to increased oil consumption if it's not functioning correctly. Keep an eye on your oil levels regularly! Ignoring this issue can lead to serious engine damage, like premature wear and even engine failure. To mitigate this, make sure you're checking your oil levels religiously and keep an eye out for any blue-ish smoke coming from the exhaust – that's a telltale sign of burning oil.

2. Engine Knocking or Misfiring

Engine knocking and misfiring are other concerns that some 2020 Ascent owners have faced. Engine knocking sounds like a metallic pinging or knocking noise coming from the engine, especially when accelerating. Misfiring, on the other hand, can cause the engine to run rough, hesitate, or even stall.

What’s causing these annoying issues? Engine knocking can occur when the air-fuel mixture in the cylinders ignites unevenly, leading to uncontrolled combustion. This can be caused by using low-octane fuel, carbon buildup in the cylinders, or issues with the spark plugs or ignition coils. Misfires can happen when one or more cylinders aren't firing properly, which can be due to faulty spark plugs, ignition coils, fuel injectors, or even vacuum leaks. If you hear knocking or feel the engine misfiring, don't ignore it! Continuing to drive with these issues can cause significant damage to the engine's internal components. Get your Ascent checked out by a qualified mechanic ASAP to diagnose and fix the problem before it gets worse. Regular maintenance, like using the recommended fuel grade and replacing spark plugs at the specified intervals, can help prevent these issues.

3. Turbocharger Problems

The 2020 Subaru Ascent is equipped with a turbocharger, which helps boost the engine's power and efficiency. However, some owners have reported issues with the turbocharger system. One common problem is a whining or whistling noise coming from the turbocharger, which can indicate a failing turbo. Other potential issues include reduced power, poor acceleration, and even turbocharger failure.

So, what's the deal with these turbo troubles? Turbochargers are complex pieces of machinery that operate at very high speeds and temperatures. Over time, the bearings and seals inside the turbo can wear out, leading to performance issues and eventual failure. Additionally, problems with the turbocharger's wastegate or bypass valve can also cause issues. If you notice any unusual noises coming from the turbocharger or experience a loss of power, get it checked out by a mechanic. Ignoring turbocharger problems can lead to major engine damage, so it's best to address them early on. Regular maintenance, such as changing the engine oil regularly and avoiding excessive idling, can help prolong the life of your turbocharger.

4. Issues with the Direct Injection System

The 2020 Ascent uses direct fuel injection, which injects fuel directly into the cylinders rather than into the intake manifold. While direct injection offers several benefits, it can also lead to some unique problems. One common issue is carbon buildup on the intake valves. Because fuel isn't sprayed onto the valves, they don't get cleaned as effectively, leading to carbon deposits that can restrict airflow and reduce engine performance.

What's the solution for this carbon conundrum? Some owners have reported success using fuel system cleaners or having the intake valves cleaned manually. Another potential issue with direct injection systems is problems with the fuel injectors themselves. The injectors can become clogged or faulty, leading to misfires, poor fuel economy, and rough running. If you suspect issues with the direct injection system, it's best to have it diagnosed by a qualified technician. They can check the fuel injectors, inspect the intake valves for carbon buildup, and perform any necessary repairs or maintenance. Keeping your fuel system clean and using high-quality fuel can help prevent these issues.

Why Do These Issues Occur?

Okay, so we've covered the common problems, but why are these issues happening in the first place? Well, there are a few potential factors at play. One possibility is related to the engine's design and manufacturing tolerances. Even small variations in the manufacturing process can lead to increased oil consumption or other problems. Another factor could be the materials used in the engine's construction. If certain components aren't durable enough to withstand the stresses of everyday driving, they may be more prone to failure.

Also, let's not forget about maintenance. Neglecting regular maintenance, such as oil changes and spark plug replacements, can exacerbate existing problems and lead to new ones. And of course, driving habits can also play a role. Aggressive driving, excessive idling, and frequent short trips can all put extra strain on the engine and increase the risk of problems. To minimize the risk of engine issues, it's crucial to follow the manufacturer's recommended maintenance schedule and drive responsibly.

What Can You Do About These Problems?

Alright, so what can you actually do if you're experiencing these engine issues with your 2020 Subaru Ascent? Here are some steps you can take:

1. Regular Maintenance: This is key! Stick to the recommended maintenance schedule in your owner's manual. This includes regular oil changes, filter replacements, and spark plug replacements. Preventative maintenance can catch problems early and prevent them from escalating.
2. Monitor Oil Levels: Keep a close eye on your oil levels, especially if you've noticed excessive oil consumption. Check the oil regularly (ideally every week) and top it off as needed. Documenting your oil consumption can also be helpful when discussing the issue with your mechanic or Subaru dealer.
3. Use Quality Fuel: Use the recommended fuel grade (usually 87 octane) and consider using a high-quality fuel brand. Some fuels contain additives that can help keep your engine clean and prevent carbon buildup.
4. Address Issues Promptly: If you notice any unusual noises, smells, or performance issues, don't ignore them! Get your Ascent checked out by a qualified mechanic as soon as possible. Early diagnosis and repair can often prevent more serious damage.
5. Contact Subaru: If you're experiencing significant engine issues, contact your local Subaru dealer or Subaru of America directly. They may be able to offer assistance, especially if your vehicle is still under warranty. Additionally, they may be aware of any recalls or service bulletins related to the engine issues you're experiencing.
6. Consider an Extended Warranty: If your factory warranty is about to expire, consider purchasing an extended warranty. This can provide peace of mind and protect you from unexpected repair costs down the road.
